Acampfire burn 2 1/2 pounds of wood per hour. how many pounds of wood do you need to keep the camp firing burning for 6 hours?

hope this helps a little bit :)

Step-by-step explanation:

Every camping enthusiast is familiar with the half inch rule. Basically, half an inch of wood equals an hour of burning time. This means if you have a ten inch piece of wood your campfire will burn for ten hours. However, the burn time can also depend on the type of wood you use since some types of wood tend to burn faster than others.

the required function is .

step-by-step explanation:

from the given table it is noticed that the graph passing through (-3,7), (0,4), (3,1) and (8,-4).

it is a linear function because the value of y is decrease by one as the value of x increase by 1.

the slope of the function is

the slope of the function is -1 and the y-intercept is 4.

the slope intercept form is

where, m is slope and b is y-intercept.

therefore the required function is . the graph of this function is shown below.

part a

x     y

0     8

1     7.5

2     7

3     6.5

4     6

5     5.5  

for every hour i deducted .5 inches from the length of the candle

part b

it is a function because for every x value there is only one y value

part   c

for every x value there is only one y value

x       y

0       8

1       7.6

2       7.2

3       6.8
